A Fire Alarm Circuit Design for Informing the Human Beings in Market Places

Abstract

This paper provides a brief description of the hardware model and outlines how it developed a fire alarm circuit for crowded areas. A straightforward circuit known as a fire alarm circuit detects fires and turns on buzzers or sirens. The use of fire alarm circuits is crucial for timely fire detection and the protection of lives and property. Security systems include fire alarm circuits and smoke sensors that aid in spotting or preventing harm. Commercial structures, including offices, movie theatres, shopping centers, and other public locations, are required to have smoke detectors and fire alarm systems. We created five extremely straightforward fire alarm circuits utilizing widely available parts like the thermistor, LM358 germanium diode, LM341, and NE555. There are many expensive and complex fire alarm circuits available as standalone devices. This is a very basic alarm circuit that uses a buzzer, an operational amplifier, and a thermostat. The main goal of a fire alarm system is to provide people with early notice of a fire so they can be prepared. Evacuating the area so that quick action may be done to reduce or end the fire effect Alarms can be set off manually or with the aid of detectors (Remotely). The work shown here is a mini-project completed by Electronics & Communication Engineering Department students at Dayananda Sagar College of Engineering in Bangalore during their second semester.
